1Multifunctional silver film with superhydrophobic and antibacterial properties显示文摘材料性质强烈依赖于材料结构。材料结构的大差异和复杂性提供重要机会改进材料的性质,扩展他们的应用。这里,我们讨论控制银粒子的成核和生长准备的一部多功能的银电影的制造。有高 hydrophobicity 和抗菌剂活动的银电影被采用一条电气化学的途径制作。依赖恐水病并且银粒子的尺寸和形状上的抗菌剂性质首先被调查。小型的银粒子展出了高抗菌剂率,当由树枝状的粒子组成的一部多孔的银电影显示出一项重要恐水病的活动时。由调整反应,时间,当前的密度,和银腌集中,有 150.9 的一个接触角度的一部银电影吗?Ping Che Wei Liu Xiaoxue Chang Anhe Wang Yongsheng Han 2016Nano Research2016,9,2:7
2Patient-derived non-small cell lung cancer xenograft mirrors complex tumor heterogeneity显示文摘Objective:Patient-derived xenograft(PDX)models have shown great promise in preclinical and translational applications,but their consistency with primary tumors in phenotypic,genetic,and pharmacodynamic heterogeneity has not been well-studied.This study aimed to establish a PDX repository for non-small cell lung cancer(NSCLC)and to further elucidate whether it could preserve the heterogeneity within and between tumors in patients.Methods:A total of 75 surgically resected NSCLC specimens were implanted into immunodeficient NOD/SCID mice.Based on the successful establishment of the NSCLC PDX model,we compared the expressions of vimentin,Ki67,EGFR,and PD-L1 proteins between cancer tissues and PDX models using hematoxylin and eosin staining and immunohistochemical staining.In addition,we detected whole gene expression profiling between primary tumors and PDX generations.We also performed whole exome sequencing(WES)analysis in 17 first generation xenografts to further assess whether PDXs retained the patient heterogeneities.Finally,paclitaxel,cisplatin,doxorubicin,atezolizumab,afatininb,and AZD4547 were used to evaluate the responses of PDX models to the standard-of-care agents.Results:A large collection of serially transplantable PDX models for NSCLC were successfully developed.The histology and pathological immunohistochemistry of PDX xenografts were consistent with the patients’tumor samples.WES and RNA-seq further confirmed that PDX accurately replicated the molecular heterogeneities of primary tumors.Similar to clinical patients,PDX models responded differentially to the standard-of-care treatment,including chemo-,targeted-and immuno-therapeutics.Conclusions:Our established PDX models of NSCLC faithfully reproduced the molecular,histopathological,and therapeutic characteristics,as well as the corresponding tumor heterogeneities,which provides a clinically relevant platform for drug screening,biomarker discovery,and translational research.Xuanming Chen Cheng Shen Zhe Wei Rui Zhang Yongsheng Wang Lili Jiang Ke Chen Shuang Qiu Yuanli Zhang Ting Zhang Bin Chen Yanjun Xu Qiyi Feng Jinxing Huang Zhihui Zhong Hongxia Li Guowei Che Kai Xiao 2021Cancer Biology & Medicine2021,18,1:5
3Azvudine is a thymus-homing anti-SARS-CoV-2 drug effective in treating COVID-19 patients显示文摘Azvudine(FNC)is a nucleoside analog that inhibits HIV-1 RNA-dependent RNA polymerase(RdRp).Recently,we discovered FNC an agent against SARS-CoV-2,and have taken it into Phase III trial for COVID-19 patients.FNC monophosphate analog inhibited SARS-CoV-2 and HCoV-OC43 coronavirus with an EC_(50) between 1.2 and 4.3 μM,depending on viruses or cells,and selective index(SI)in 15-83 range.Oral administration of FNC in rats revealed a substantial thymus-homing feature,with FNC triphosphate(the active form)concentrated in the thymus and peripheral blood mononuclear cells(PBMC).Treating SARS-CoV-2 infected rhesus macaques with FNC(0.07 mg/kg, qd,orally)reduced viral load,recuperated the thymus,improved lymphocyte profiles,alleviated in flammation and orga n damage,and lessened grou nd・glass opacities in chest X-ray.Sin gle-cell seque ncing suggested the promotion of thymus function by FNC.A randomized,single-arm clinical trial of FNC on compassionate use(n=31)showed that oral FNC(5 mg,qd)cured all COVID-19 patients,with 100%viral ribonucleic acid negative conversion in 3.29±2.22 days(range:1-9 days)and 100%hospital discharge rate in 9.00±4.93 days(range:2-25 days).The side-effect of FNC is minor and transient dizziness and nausea in 16.12%(5/31)patients.Thus,FNC might cure COVID-19 through its anti-SARS-CoV-2 activity concentrated in the thymus,followed by promoted immunity.Jin-Lan Zhang Yu-Huan Li Lu-Lu Wang Hong-Qi Liu Shuai-Yao Lu Yong Liu Ke Li Bin Liu Su-Yun Li Feng-Min Shao Kun Wang Ning Sheng Rui Li Jin-Jin Cui Pei-Chun Sun Chun-Xia Ma Bo Zhu Zhe Wang Yuan-Hao Wan Shi-Shan Yu Yongsheng Che Chao-Yang Wang Chen Wang Qiangqian Zhang Li-Min Zhao Xiao-Zhong Peng Zhenshun Cheng Jun-Biao Chang Jian-Dong Jiang 2022Signal Transduction and Targeted Therapy2022,7,1:3
4Fusagerins A–F,New Alkaloids from the Fungus Fusarium sp.显示文摘Fusagerins A–F(1–6),six new alkaloids including a unique one with the rare a-(N-formyl)carboxamide moiety(1),a hydantoin(imidazolidin-2,4-dione)derivative(2),and four fungerin analogues(3–6),were isolated from the crude extract of the fungus Fusarium sp.,together with the known compound fungerin(7).Compound 2 was isolated as a racemate and further separated into two enantiomers on a chiral HPLC column.The structures of 1–6 were determined mainly by NMR experiments,and the absolute configuration of 1 and 2 was assigned by electronic circular dichroism(ECD)calculations.Compound 7 showed antibacterial activity against Staphylococcus aureus and Streptococcus pneumoniae,and weak cytotoxicity against the T24 cells.Hao Wen Yan Li Xingzhong Liu Wencai Ye Xinsheng Yao Yongsheng Che 2015Natural Products and Bioprospecting2015,5,4:2
5Multi-Omics-Guided Discovery of Omicsynins Produced by Streptomyces sp.1647:Pseudo-Tetrapeptides Active Against Influenza A Viruses and Coronavirus HCoV-229E显示文摘Many microorganisms have mechanisms that protect cells against attack from viruses.The fermentation components of Streptomyces sp.1647 exhibit potent anti-influenza A virus(IAV)activity.This strain was isolated from soil in southern China in the 1970s,but the chemical nature of its antiviral substance(s)has remained unknown until now.We used an integrated multi-omics strategy to identify the antiviral agents from this streptomycete.The antibiotics and Secondary Metabolite Analysis Shell(antiSMASH)analysis of its genome sequence revealed 38 biosynthetic gene clusters(BGCs)for secondary metabolites,and the target BGCs possibly responsible for the production of antiviral components were narrowed down to three BGCs by bioactivity-guided comparative transcriptomics analysis.Through bioinformatics analysis and genetic manipulation of the regulators and a biosynthetic gene,cluster 36 was identified as the BGC responsible for the biosynthesis of the antiviral compounds.Bioactivity-based molecular networking analysis of mass spectrometric data from different recombinant strains illustrated that the antiviral compounds were a class of structural analogues.Finally,18 pseudo-tetrapeptides with an internal ureido linkage,omicsynins A1–A6,B1–B6,and C1–C6,were identified and/or isolated from fermentation broth.Among them,11 compounds(omicsynins A1,A2,A6,B1–B3,B5,B6,C1,C2,and C6)are new compounds.Omicsynins B1–B4 exhibited potent antiviral activity against IAV with the 50%inhibitory concentration(IC_(50))of approximately 1μmol·L^(-1)and a selectivity index(SI)ranging from 100 to 300.Omicsynins B1–B4 also showed significant antiviral activity against human coronavirus HCoV-229E.By integrating multi-omics data,we discovered a number of novel antiviral pseudo-tetrapeptides produced by Streptomyces sp.1647,indicating that the secondary metabolites of microorganisms are a valuable source of novel antivirals.Hongmin Sun Xingxing Li Minghua Chen Ming Zhong Yihua Li Kun Wang Yu Du Xin Zhen Rongmei Gao Yexiang Wu Yuanyuan Shi Liyan Yu Yongsheng Che Yuhuan Li Jian-Dong Jiang Bin Hong Shuyi Si 2022Engineering2022,,9:0
